Anyone who understand the concept of bitcoin investment will never be tempted to sell his holdings whenever there's a massive increase in the price of bitcoin. Even if they will be tempted to sell due to one or two reasons but not to the extent of selling all thier bitcoin investment, As a bitcoin investor is advised to sell some portion of your holdings and then allow it to compound upon itself or keep accumulating more bitcoin to enable you fill the missing space rather than selling all your holdings and start fucking around or looking for a way to start building back your bitcoin portfolio, because the price might get to a certain point where you will be thinking on where to start from and this can probably make you lose interest in bitcoin investment.
It is not wrong to sell some of your holdings if you have already achieved your goal and have enough Bitcoin. However, if you are in the early stages of investing or have not yet achieved your goal or accumulated enough Bitcoin, it is better not to focus on selling. Bitcoin investment is not something that you just invest in, rather you can enjoy the investment or use it in real life after achieving your goal.
I cannot give any specific advice to investors who have accumulated enough Bitcoin or achieved their goal. Because they are already experienced and may be more knowledgeable than me. But for those who have not yet achieved their goal, it would be better not to express interest in selling Bitcoin, even if it is partial. Keep investing consistently to achieve your goal and fight to achieve your goal.
